Always blocking tristate driving signal <A> in unit <LAN_IDE_CP> is removed. Input <DS0> is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. Input <DS1> is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. Input <FCS> is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. Input <Z3> is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. Input <MTCR> is never used. This port will be preserved and left unconnected if it belongs to a top-level block or it belongs to a sub-block and the hierarchy of this sub-block is preserved. Signal <LAN_INT_D0> is never used or assigned. This unconnected signal will be trimmed during the optimization process. Signal <DTACK_S> is never used or assigned. This unconnected signal will be trimmed during the optimization process. You have specified state <nop> as a recovery-only state for the safe implementation of FSM <LAN_RST_SM>. Due to a limitation in this version of the software, the logic required to implement this recovery-only state might not be properly generated.
